Official Title

Assessment of the Utility of Vibration Response Imaging (VRI) in Evaluating Dyspnea Patients Presenting to the Emergency Department

Brief Summary

For the patient with acute dyspnea in the ED, early differentiation between CHF and non-CHF causes is essential for proper management. The capacity to triage patients quickly and accurately has a beneficial impact upon outcome, disposition, stratification and length of stay in the ED and required length of hospital admission.

The ability to assess pulmonary status rapidly by quantitative regional vibration technology offers significant potential advantage for earlier diagnosis. The VRI technique may provide a quick and accurate method of differentiating between dyspnea due to HF and dyspnea due to pulmonary causes; thereby improving management and outcomes.

Eligibility Criteria

Inclusion Criteria:

• Able and willing to provide Informed Consent;

  ->40 years of age;

• Estimated Body Mass Index >19;

• Patient presented to the emergency department with a chief complaint of acute dyspnea.

Exclusion Criteria:

• Patients with obvious trauma or acute anxiety as a cause of dyspnea;
• Patient has already received directed therapy in the ED and symptoms are remarkably improved;
• Physician concern regarding possible harm to patient caused by positioning or ambulating the patient for VRI testing;
• Intubated or mechanically ventilated;
• Acute hemodynamic or ventilator instability requiring immediate resuscitation;
• Body habitus or skin condition that might prevent the placement of the sound sensors on the back (e.g. severe scoliosis, kyphosis, chest wall deformation, skin lesion on the back or compression fracture);
• Hirsutism.
